Assignment #4
· All assignments must be submitted via Blackboard by the deadlines in order to receive credits.
· For homework assignments, you are allowed unlimited submissions before the deadlines.
· No partial credits will be awarded. Your solution is either correct or incorrect.
Ava’s company is in the process of designing and building one new local area network to support the newly expanded branch dedicated to provide bookkeeping services to 1000+ businesses/companies. All transactions and data records must be kept confidentially.
A list of networking devices has been sent to you for your approval. This list includes 4 types of networking devices: hub, switch, router and firewall.
You are asked to either approve or disapprove each of these 4 types networking devices.
For every type of networking device that you disapprove, you must provide at least one reason to support your decision.
You do not need to provide any reason for the device that you approve.
Please read and understand the “Hint” part of this assignment closely before you submit your solution. If you did not, your solution most likely is incorrect.
Hint:
· You are NOT asked to provide definitions nor capabilities of these devices, because you are required to fully understand these devices; otherwise, your decision cannot be right.
· You are NOT asked to make a selection or recommendation, because making a selection or recommendation concerns the cost. There is no mention of “cost” in the requirements.
· There is no mention of “performance” nor “traffic” in the requirements. If your solution talks about performance or efficiency, your solution is incorrect.
· If a device can satisfy the requirements, it cannot be disapproved, regardless its capability, performance, intelligence, or cost.
· No partial credits can be awarded. Why? If you made incorrect decisions, the new network will FAIL to satisfy the business and will put the business at risks. You may be asked to pay back the business loss. You will be fired. Yet, you would still ask for partial credits??!!
· A reason is a fact and is not an opinion. For example, “….not flexible…”, “…poor performance…”, “…more expensive….” are opinions.
· There is only one correct solution.
· Your solution is incorrect, if:
· You disapproved a device for an incorrect reason.
· You approved a device that will put Ava’s business at risks – You did not fully understand the device that you approved or you did not fully understand Ava’s business requirements.
· You disapproved a device without providing your reason(s).
· You included at least one incorrect statement in your solution; for example, 1 day has 36 hours or Internet is the same as World Wide Web.
